Partnoids, today I bring you my latest design of the 3x3 door. It was a fair while back when I uploaded my first circuit and since then things have changed!

This unit is only 7x3 in footprint compared to the 8x8 of my old door; It's also based on a flip-flop design that eliminates the need for an external toggle circuit meaning you can hook as many buttons up to it as you want! Hopefully all this makes the build easier to construct and less resource heavy for you in your own worlds!
